I guess the next problems will be re-enabling all of the 'Services' that are now disabled since getting rid of MBS and then getting System Restore to work. (At the moment my friend is unable to go back past 1.6.07 to try another restore point).

He has not made any himself but I understood XP made its own every now and then but none appear to have been made.

Plus everything being done over the phone, which makes it a little awkward.
